Abstract (en)

[origin: US2019163606A1] The present disclosure provides a checking method of a system start-up file. The method includes: acquiring the system start-up file and a mapping table from a system firmware partition; reading first check data and addressing data associated therewith from the mapping table; reading segmentation data corresponding to the first check data from the system start-up file according to the addressing data; determining whether the first check data is a first type or a second type; if it is the first type, determining whether the segmentation data is a repeated permutation of the first check data, and if not, a security error exists in the system start-up file; and if it is the second type, determining whether second check data, obtained by calculating the segmentation data according to a check algorithm, is consistent with the first check data, and if inconsistent, a security error exists in the system start-up file.
